LCD Panel Operation

This chapter explains how to place and receive calls using the U-
336S/SA front panel. An introduction to the panel operation of your
modem is presented. Your modem comes with a menu driven 20 x 2
LCD display. All functions of the modem are displayed and selectable
from this menu. Finally, this chapter will familiarize the user with the
menu tree structure which categorizes modem operations for easy and
quick reference. Modem users can also use the panel menu operations
and use the equivalent AT commands listed in this chapter.
If you use your modem with a PC the factory default settings should be
just right for you. Connect the modem according to the instructions in
Chapter 2, install the communication software, follow the instructions in
this chapter, and you're all set!

LCD Panel

The modem's actions, options, and parameters can be set, changed,
and viewed from the front panel, or viewed and changed through AT
commands by the computer or terminal connected to the modem. We
will discuss panel operations in this chapter with reference to equivalent
AT commands. Note that in most cases you will use your
communication software to send AT commands to your modem. Only
in very rare circumstances will it be necessary to use the modem's
panel.
Once turned on, the modem goes into the Idle Screen state (except if a
leased line is selected). It then waits for commands from a
